Tyrannioware Python Implementation

12th July 2002

Tyrannioware
is Aaron Lav's bibliographic cataloguing suite, written in Python.
One of things it does is fetch MARC records from the Library of
Congress using Z39.50, so Aaron separated out the Z39.50 component
of his software behind a ZOOM API, and has made it generally
available.

It is a pure Python project: the ASN.1 compiler, the BER encoder and
decoder and everything else is written from the ground up in Python:
the low-level libraries are
also
available.
As if that weren't enough, versions from 0.9 onwards also contain
a graphical
Zthes
browser, which was written to test the python GRS-1 implementation.
